Client's on the phone — can they still fund a SEP-IRA for last year before the extended deadline?
TaxFigure
Yes. A SEP-IRA can be established and funded up to the employer's extended return due date under IRC §408(k) — for a sole proprietor on extension, that's October 15. The deduction limit is the lesser of 25% of net self-employment earnings or the annual cap.

The Solo CPA Advantage

You're the whole firm.
Now you have a research desk.

No associates to delegate to, no library down the hall — just you and the next deadline. TaxFigure is the research department a solo practice could never afford to staff.

Answer it on the call

Stop saying "let me get back to you"

Pull a citeable answer while the client is still on the line — and sound like the firm with a research team behind it, because now you have one.

Before you sign

Validate every position before you file

Check the gray-area treatment against primary authority — IRC, Treasury Regs, rulings, and case law — so the return is defensible the day you sign it.

Through the season

Busy season, without the bottleneck

When deadlines pile up and the gray-area questions keep coming, the cited answer arrives in the time it takes to scan the next return.

One Engine · Five Workflows

From the first question to the final resolution

Move across the entire engagement without leaving the platform — or losing context. Every answer, model, and review is anchored to the same citeable authority.

Research

Citeable answers

Federal, state & municipal authority in seconds — the answer arrives before the client finishes the question.

Planning

Multi-year strategy

Entity selection, retirement sequencing, and year-end strategy — the advisory work clients actually pay extra for.

Modeling

What-if, quantified

Roth conversions, §199A optimization, basis & waterfalls — quick enough to model mid-meeting.

Reviews

Return review

Missed deductions, position validation, multi-state nexus — caught before the return ships, not after busy season ends.

Resolution

Notice & audit response

Penalty abatement, reasonable cause, and audit support — handled in-house instead of referred out.

Where Solo CPAs Win

Research at the speed of
a client conversation

The hard questions don't wait for a quiet afternoon — they come up mid-call, mid-review, mid-season. TaxFigure keeps up with the way a solo practice actually runs.

Second-guessing a deduction or an election? Validate it against primary authority in seconds.

Your own second opinion

No partner to sanity-check a tricky position — so let the authority do it. Cross-checked, cited, neutral.

Through the busy-season crush

When every hour counts, research that took two hours takes two minutes — and the season gets survivable.

Why It Feels Different

Research you can stand behind

Other tools give you a paragraph. TaxFigure gives you a paragraph with its sources attached — and the trail to prove it.

Citeable authority

Every answer carries its sources

Cite the IRC section straight to the client. Anchor the position before you sign. Your one-person firm leaves the paper trail a national firm does.

Natural language

Ask in plain English the way you'd ask the colleague you'd hire if you could — no query syntax, no learning curve.

Multi-jurisdiction

Take the client who just moved states without taking on a research project. Every state, one query, no extra subscriptions.

Every answer timestamped and source-anchored — workpaper-quality documentation without writing workpapers.

Workflow memory

Pick up the client file where last call left off — the platform remembers, so you don't have to start over every time.

Coverage

In the moment

Built for the question that
walks through the door

Your hardest open call
Client on hold
A SEP-IRA deadline. A multi-state K-1. A worker-classification gray area. The client wants an answer — and you need it cold.
With TaxFigure
Cited on demand
The IRC section, the regulation, the rev. ruling — assembled around the question and ready to send back as the firm's position.

When the next client question is the work, TaxFigure makes you the firm with an answer ready — not the one promising to get back to them.

Common Questions

Solo CPA questions, answered

What solo practitioners ask before bringing TaxFigure into their practice.

Can TaxFigure answer a tax question while my client is still on the phone?

Yes — that's the core use case. Ask in plain English and the answer arrives in seconds as a bottom-line-up-front summary with inline citations, fast enough to resolve most questions during the call instead of promising to get back to them.

Does TaxFigure cite primary authority I can verify?

Every answer includes inline citations and a sources panel linking to the underlying authority — IRC sections, Treasury Regulations, rulings, and caselaw — so you can click through and verify the primary source before you rely on it.

What documents can I upload, and what happens to them?

PDF, Word, Excel, CSV, and image files (JPG/PNG) up to 10 MB each — W-2s, 1099s, K-1s, prior-year returns, receipts, and IRS correspondence. Documents are OCR-processed, classified, and auto-categorized into income, deductions, assets, and compliance, then become available to chat, insights, and checklists.

Can it act as a second opinion on a position before I file?

Yes. Ask it to validate a deduction, election, or gray-area treatment and it checks the position against current law and guidance, returning a cited answer you can keep with the file as documentation.

What client types does it handle?

Each client is an entity with its own isolated workspace — individuals, LLCs, S-corps, partnerships, and trusts — so answers are scoped to that client's structure, tax year, and uploaded documents rather than generic guidance.

How is my client data protected?

Client PII is detected and tokenized before it ever reaches a model, and every entity workspace is isolated per client — the per-client confidentiality treatment a practice's §7216 obligations expect.
